Viewing the High-Energy Universe with the Fermi Gamma-ray Space Telescope

Frontiers in Optics 2010/Laser Science XXVI, 2010
The Fermi Gamma-ray Space Telescope has completed 2 years of observations of the entire sky from 10 keV to more than 300 GeV, providing a new view of the high-energy Universe.

Status of the technology of the current space missions including the Fermi gamma-ray space telescope

Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 2010
Abstract We review the status of X-rays and γ -rays space missions operational in 2009. We provide highlights of the current semiconductor technology instrumentation and briefly discuss challenges to be addressed by future missions.

Some highlights of the first four years of the Fermi Gamma-ray Space Telescope

Frontiers of Physics, 2013
The Fermi Gamma-ray Space Telescope, formerly called GLAST, measures the cosmic gamma-ray flux in the energy range 8 keV to > 300 GeV. In addition to breakthrough capabilities in energy coverage and localization, the very large field of view enables observations of 20% of the sky at any instant, and the entire sky on a timescale of a few hours.

Fermi Gamma-ray Space Telescope Observations of the Gamma-ray Outburst from 3C 454.3 in November 2010

2011
The flat-spectrum radio quasar 3C 454.3 underwent an extraordinary 5-day gamma-ray outburst in November 2010 where the daily flux measured with the Fermi Large Area Telescope (LAT) at photon energies E>100 MeV reached (66+/-2) x 10^-6 ph cm^-2 s^-1. The 3-hr peak flux corresponded to an apparent isotropic luminosity of (2.1+/-0.2)x10^50 erg s^-1, the ...
